Answer:
0.45 moles of air are in a 3.0 L balloon
Explanation:
The given problem can be solved by using unitary method.
Firstly, we have to find out how many breaths are equivalent to 3.0 L. Secondly, we have to find out how many moles of air are supplied corresponding to the calculated number of breaths.
1.2 L = 3 breaths
So, 3.0 L = 
breaths = 7.5 breaths
1 breath supplies 0.060 moles of air
So, 7.5 breaths supplies 
moles of air or 0.45 moles of air.
Hence, 0.45 moles of air are in a 3.0 L balloon.
When the water is heated, the water molecules bounce around and spread out.
When the water is normal, they are pretty close-knit but still flow around.
When the water is frozen, they are frozen in place and do not move.
I hope this helped :)

Explanation:
The orbital period is the time a given cosmic question takes to finish one circle around another protest and applies in space science as a rule to planets or space rocks circling the Sun, moons circling planets, exoplanets circling different stars, or double stars. Mercury, for instance, has an orbital time of 88 days while it takes Jupiter around 11.86 years. The time of the Earth's circle is generally thought to be 365 days as timetables appear.
They are on the left side of the equation.
